At the ZSL London Zoo there’s a new King of the Jungle – or at least of the jungle enclosure. Kumbuka, a 15-year-old silverback western lowland gorilla, arrived in London two weeks ago from the Paignton Zoo in Devon, England.

The zookeepers hope that the 400-pound gorilla will mate with the zoo’s gorillas to boost the number of the endangered species in the Europe breeding program, according to the zoo.

According to Endangered Species International, there are currently around 100,000 western lowland gorillas in the world. They are considered “critically endangered.”

“We’re all really excited by the arrival of Kumbuka here at ZSL London Zoo and he’s settling in really well,” said the gorilla keeper Daniel Simmonds in a press release. “We’ve been slowly introducing him to our three females, and Mjukuu and Effie are already quite smitten with their handsome new roommate.”

The European Endangered Species Programme helps manage the population of threatened species by swapping breeds from zoos. Kumbuka is filling the void left by male Kesho, who was moved to Longleat Safari Park to be with his brother Alf.
